Answer:

y = -x + 4

Step-by-step explanation:

Mathematically, the equation of a straight line is;

y = mx + b

where m is the slope and b is the y-intercept

from the plot, the y intercept is 4

So we have;

y = mx + 4

To get the value of m, we substitute the coordinates of any point and solve for m

we select the point; (4,0)

so;

0 = m(4) + 4

4m = 0-4

4m = -4

m = -1

so the equation of the line is;

y = -x + 4

WHAT ARE CONGRUENCE LINES

Sergeeva-Olga [200]

Answer:

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. ... Rays and lines cannot be congruent because they do not have both end points defined, and so have no definite length.

7m -- 4 for m = 8 Evaluate the following algebraic expression

arsen [322]

I don’t understand the question
If you mean
7m-4
M=8, this is the solution
7(8)-4
56-4
=52
But if you mean
7m- - 4
As in - + - = +
Then this is your answer
7(8)+4
56+4
=60

Describe what is meant by a sampling unit. Explain why the sampling unit for verifying the existence of recorded sales differs f

xeze [42]

Answer:

Step-by-step explanation:

The sampling unit is the population item from which the auditor selects sample items. The major consideration in defining the sampling unit is making it consistent with the objectives of the audit tests. Thus, the definition of the population and the planned audit procedures usually dictate the appropriate sampling unit.

The sampling unit for verifying the existence of recorded sales would be the entries in the sales journal since this is the record the auditor wishes to validate.

The sampling unit for testing the possibility of omitted sales is the shipping document from which sales are recorded because the failure to bill a shipment is the exception condition of interest to the auditor.

Please help and explain question 12

il63 [147K]

The sunflower is 2.387 meters tall.

The question is asking: which rounding will result in the greatest value?

To see, we need to round 2.387 to meter, tenth meter, and hundredth meter.

Meter - 2 meters

Tenth meter - 2.4 meters

Hundredth meter - 2.39 meters

As you see, rounding to the tenth meter gives the greatest value of 2.4. Therefore, Bahir should use a decimal rounded to the tenth meter.
